The Evolution of Tornadic Storms
Publisher: American Meteorological Society
Abstract: A life cycle classification for severe local storms is proposed, which adds a fourth stage, the quasi-steady SR Mature Stage, to the well-known Byers-Braham classification. A combined analysis of the surface weather and ...
Airflow and Precipitation Trajectories Within Severe Local Storms Which Travel to the Right of the Winds
Publisher: American Meteorological Society
Abstract: A kinematic airflow model is proposed for severe local storms which travel to the right of the winds in the middle troposphere. The model is an extension of that proposed by Browning and Ludlam (1962), and represents an ...
Conceptual Models of Precipitation Systems
Publisher: American Meteorological Society
Abstract: Imagery from radars and satellites is one of the main ingredients of nowcasting. When used to provide very detailed forecasts of precipitation for a few hours ahead, the imagery needs to be interpreted carefully in terms ...
Initiation of Precipitation in Vigorous Convective Clouds
Publisher: American Meteorological Society
Abstract: The origin of a severe local storm is traced back to a cluster of three shower cells, each of which produced a fist radar echo close to the ?30C level. This level is much higher than that associated with the majority of ...
Velocity Characteristics of Some Clear-Air Dot Angels
Publisher: American Meteorological Society
Abstract: The nature of the targets responsible for certain clear-air dot angel echoes, and their suitability as wind tracers, are deduced from pulse Doppler radar observations of their velocity characteristics. The angel echoes ...
Wind Tunnel Tests of Simulated Spherical Hailstones with Variable Roughness
Publisher: American Meteorological Society
Abstract: Wind tunnel test data on the relationship between drag coefficient and Reynolds number are presented for solid spherical models with different roughness parameters. Using a wind tunnel with minimal free-stream turbulence ...
The Oblateness of Large Hailstones
Publisher: American Meteorological Society
Abstract: Ninety large oblate hailstones have been photographed to display thin sections containing their minor and major axes. The ratios of their minor to major axes have been determined throughout their growth from the shapes of ...
Increasing Throughput in Fused Deposition Modeling by Modulating Bed Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Additive manufacturing (AM) techniques, such as fused deposition modeling (FDM), are able to fabricate physical components from three-dimensional (3D) digital models through the sequential deposition of material onto a ...
